Elevated T2-values in MRI of stroke patients shortly after symptom onset do not predict irreversible tissue infarction . Brain (2012) 135 ( Pt 6 ):1981–9.10.1093/brain/aws079 [ Cross Ref ]S. Siemonsen, U. Lobel, J. Sedlacik, N. D. Forkert, K. Mouridsen, L. Ostergaard, G. ...
The CT scan consisted of 10-mm-thick contiguous axial slices, and the MRI was performed using a 1.5-T MR scanner. Both imaging modalities were evaluated for ventricular, sulci, and fissure prominence, increased white matter T2 signal, and delayed myelination based on a gross visual assessment ...
Brain MRI was performed on the day of admission by a 3.0T magnet scanner (GE Medical Systems, Waukesha, WI, USA). Sequences included T1-weighted, T2-weighted, FLAIR and DWI sequences. All MRI scans were evaluated by an neurologist specialized in stroke (Huo, YC with 6 years experiences)...
The high-affinity TSPO ligand [18 F]GE180 was first used by Albert and colleagues for TSPO-PET imaging of untreated and pretreated GBM and showed remarkably high tumor-to-background contrast and TSPO-PET signal even in areas without contrast-enhancement on MRI [2]. This study was then ...
Panels D-F show an analogous sequence of brain MRI images from a younger AOA2 patient with 7-year disease duration (P2062). Note the moderate atrophy of the vermis and mild atrophy of the anterior portion of the cerebellar hemispheres without abnormal signal intensity. The midbrain was normal...
have indicated that MIP images from TOF-MRA can also identify IPH as a high intensity signal (HIS) in the plaque [14, 15]. This finding raises the possibility of an additional application of MIP images from TOF-MRA for the investigation of carotid artery stenosis. However, these studies ...
For all patients, a coronal DW sequence, a steady-state free precession (SSFP) sequence, and conventional T1- and T2-weighted turbo spin-echo sequences were obtained. Seven of the 10 patients had elevated signal intensity in the left hippocampal region on DW MRI; moreover, 3 of these 7 ...
Twenty-two study participants had increases in wall thickness ( 14 ), T2-weighted signal intensity ( 11 ), and/or contrast enhancement values ( 7 ) that were >2 standard deviations (SDs) from control group mean values. Ten subjects in this group had evidence of focal plaques in the ...
psychiatric disorders, such as bipolar disease.33 It should also be noted that CSF tends to have a more prominent lactate signal than brain tissue in some pathological conditions,22 which may be because of a combina- tion of higher concentration and/or longer T2 relaxation time in CSF fluid....
All MRI axial scans were acquired with a section thickness of 2 mm, an FOV of 14 cm × 14 cm, a matrix size of 256 × 256, and an in-plane resolution of 0.54–0.55 mm. The longitudinal coverages of the black-blood (T1-weighted, T2-weighted, and 3D MPRAGE)...
